The bigger the boom, the better! At the highest ranks, a proficient expert can craft a potent bomb or ten and lob them all at even the most dangerous of marauding foes, dropping the enemy before engaging in closer combat. Are you a fan of mines? Do you enjoy using V.A.T.S. to shoot grenades or mines close to or carried on an enemy? Then think about this perk.Fallout 4 Vault Dweller's Survival Guide description

Demolition Expert is a Perception perk in Fallout 4.

Taking ranks of this perk increases damage caused by explosives.

The perk affects most thrown grenades, mines, explosive weapons and weapons with the Explosive legendary effect. However, it only affects the primary damage type of a weapon. For example, a grenade that deals two types of damage only has its primary damage increased. This also means the perk does not affect the damage of pulse mines and pulse grenades, as they only deal secondary energy damage.

Notes[]

  • With rank 2, the "gain a throwing arc" effect presents as a green trail similar to what's made by the VANS perk but more solid, used to indicate a grenade's trajectory and initial landing point, though if thrown against a wall or ceiling, especially with baseball grenades, it will bounce and end up elsewhere than the guided landing point.
  • Taking rank 3 increases the explosion radius by 25%.
  • This perk does not affect the Explosive Vent Power Armor mods.
